GWR 645 Class
The GWR 645 Class was a class of designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start. Construction The whole class was delivered in nine lots, as follows: * 645-655, plus one (Lot O, 1872) * 656, 757-763, plus four (Lot P, 1872-3) * 764-775 (Lot Q, 1873) * 1501-1512 (Lot A2, 1878) * 1513-1524 (Lot B2, 1878-9) * 1525-1536 (Lot D2, 1879) * 1537-1548 (Lot E2, 1879–80) * 1549-60 (Lot F2, 1880) * 1801-1812 (Lot G2, 1881) Three of the un-numbered engines plus No. 767 were sold to the ...

George Armstrong (engineer)
George Armstrong (5 April 1822 – 11 July 1901) was an English railway engineer. He was in charge of standard gauge steam locomotives for the Great Western Railway at Wolverhampton railway works, Stafford Road Works, Wolverhampton, from 1864 to 1897. He was the younger brother of his colleague Joseph Armstrong (engineer), Joseph Armstrong, but thanks to the special requirements of the GWR at a time when it was split in two by the broad gauge, broad and standard gauges, the brothers were able to work largely independently of each other. George is best remembered for his 0-4-2 and 0-6-0 tank engines; these were long-lived, and even when life-expired they were replaced by Charles Collett, Collett and Frederick Hawksworth, Hawksworth with remarkably similar locomotives, the well-known GWR 1400 Class, 1400, GWR 5700 Class, 5700 and GWR 1600 Class, 1600 classes. Biography George Armstrong was born on 5 April 1822. His gravestone states that the place was Bewcastle, Cumberland, and this ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.

Railway Locomotives Introduced In 1872
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Correspondence And Travel Society
The Railway Correspondence and Travel Society (RCTS) is a national society founded in Cheltenham, England in 1928 to bring together those interested in rail transport and locomotives. Since 1929 the Society has published a regular journal ''The Railway Observer'' which records the current railway scene. It also has regional branches which organise meetings and trips to places of interest and an archive & library. It has published definitive multi-volume locomotive histories of the Great Western, Southern and London & North Eastern Railways, and has in progress similar works on the London, Midland & Scottish Railway and British Railways standard steam locomotives. It also has published many other historical railway books since the mid-1950s. On 2 November 2016, the RCTS become a Charitable Incorporated Organisation (CIO), registered number 1169995. Its new Archive and Library (located within the former station-master's house at Leatherhead station) was opened on 6 October 20 ...

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

GWR 0-6-0PT
The GWR 0-6-0PT (Pannier Tank), is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines. The early examples, such as the 1901 and 2021 classes, were rebuilt from saddle or side tanks when the locos received a Belpaire firebox – this type of firebox has a square top and is incompatible with a curved saddle tank. This process mostly took place during the tenure at Swindon Works of George Jackson Churchward. Only a very small number of saddle tank locomotives escaped rebuilding as panniers, notably the 1361 Class built new under Churchward in 1910, by which date a few of the 1813 Class had already been rebuilt as pannier tanks. Classification The GWR pannier tank locomotives were classified as follows: Small engines (wheelbase under 15' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotives Of The Great Western Railway
The first Locomotives of the Great Western Railway (GWR) were specified by Isambard Kingdom Brunel but Daniel Gooch was soon appointed as the railway's Locomotive Superintendent. He designed several different broad gauge types for the growing railway, such as the Firefly and later Iron Duke Class 2-2-2s. In 1864 Gooch was succeeded by Joseph Armstrong who brought his standard gauge experience to the workshops at Swindon. To replace some of the earlier locomotives, he put broad gauge wheels on his standard gauge locomotives and from this time on all locomotives were given numbers, including the broad gauge ones that had previously carried just names. Joseph Armstrong's early death in 1877 meant that the next phase of motive power design was the responsibility of William Dean, his assistant and successor. Dean went on to develop express 4-4-0 types, but the familiar 4-6-0s of later years were initially introduced by the next engineer, George Jackson Churchward. He was also res ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds (rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * Engine displacement Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the ... References {{Steam engine configurations Engine technology ...

Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Tire
The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel. Installation Replacing a whole wheel because of a worn contact surface was expensive, so older types of railway wheels were fitted with a replaceable steel tire. The tire is a hoop of steel that is fitted around the steel wheel centre. The tire is machined with a shoulder on its outer face to locate it on the wheel centre, and a groove on the inside diameter of the flange face. The inside diameter of the tire is machined to be slightly less than the diameter of the wheel centre on which it is mounted, to give an interference fit. The tire is fitted by heating to a controlled temperature, avoiding overheating. This causes the tire to expand. The wheel centre, usually already mounted on the axle, is lowered into the tire which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
